TIRE.

Application filed July 31,

To all' @07mm 'it may coaoera:

Be it known that I, JOHN ALFRED GnnoMn, a citizen of the Republic ofSwitzerland, residing at Kitchener, Vin the Province of @ntario andDominion of Canada, have invented new and useful linproveinents inTires, of which the following is a specification.

This invention relates to an improvement in tires for automobiles andthe like, the principal object of the invention being to insert springsin the tire for preventing collapsing of the same under the load andalso preventing cutting of the tire.

Another object of the invention is to place the springs between theplies of fabric ofthe tire with spaces between the springs of eachannular row. A

This invention also consists in certain other features of constructionand in the combination and ar angement of the several parts., to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

l'n describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which 4.Figurel is a fragmentary view of a tire constructed in accordance with myinvention and having portions broken away to show the interiorconstruction thereof.

Figure 2 is a section on line 2-2 of Figure l, taken circumferentiallyof the tire.

Figure 3 is a view of one of the springs.

ln these views l indicates the tire casi ng which may be formed in theusual manner and is composed of a number of plies 2 of rubberized fabricand the rubber tread 3. ln carrying out my invention l place springs abetween the plies,each spring being formed of the same cross sectionalshape as the tire,

shown i-n Figure 3.

rlhe tire is built in the ordinary way but after the first ply ofrubberized fabric is put on the core and rolled down an annular row ofsteel springs 4 is placed in position on this fabric. Each spiing iscontained within a rubber jacket 5. These springs are spaced apart asshown. These springs must be long enough to come down against the inneredge of the core. Then the second ply of material Specification ofLetters Patent.

is placed in position over the first ply and the springs and thenasecondrow of springs, contained in rubber jackets, is placed over the secondply. These springs are alternately arranged with the springs of thefirst row. The third ply of fabric is then placed in position over thesecond row of springs and then a third row of springs is placed on thisthird ply with the springs located above the spaces between the springsof the other two rows. The springs of the outer row are spaced apart adistance equal to the width ci the spring and the springs or the in nerrows are arranged in radial alignment with such spaces, as clearly shownin Figure 2. Thus a sharp object' cannot be forced through the tirewithout striking one of the springs. rlhe fourth ply of material is thenput in position and rolled down and the rest of the tire built up thesaine as usual. YAll the springs must be long enough to come downagainst the inner edge of the core and.

desired a greater number of plies of fabric may be used and also agreater number of rows of springs may be used.

rlhe springs will prevent collapsing of the tire so that the tire may beused without an inner; tube, though, of course, a tube can be used ifdesired and in this case the springs would act as an armor and preventpunctures or blowouts of the tube.

[is will be seen the springs will act to carry the load in a resilientmanner and will add greatly to the life of the tire.

lt is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

T desire it to be under T muv i ,ood that .i make changes in theconstruction and in theI combination and arrangement of the severalparts, provided that such changes fall within the scope of the appendedclaim.

lWhat l claim is A tire casing formed with a number of plies of fabric,a row of metal springs placed between each pair of plies, a jacket of lresilient material enclosing each spring, the springs of the outer rowbeing spaced apart a distance equal to the width of a spring and thesprings of the inner rows being arranged in radial alignment 'with saidspaces.

ln testimony whereof I aiX my signature.

JOHN ALFRED GERUME.
